VEHICLE WHEEL.

Application filed April 30, 1917. Serial No. 165,383.

The invention relates to vehicle wheels of the wooden spoke type, and it is the object. of the invention to avoid certain objections incident to the use of a wooden telly. To this end the invention comprises the novel construction and combination of a metallic telly and wooden spokes, and the method of assembling the structure. as hereinafter set forth.

in the drawings:

Figure l'is a cross-section of a wheel em'bodyinginy improvement, and provided with a combined metallic telly and clincher rim;

/ Figure 2 is a similar view, showing the metallic telly and-demountable rim;

Figure lion shown in Figure 2;

Figure 4 illustrates the manner of assembling the spokes and rim;

Figure 5 is a section showing a modified construction,

In the nresent state of the art it is usual to proviue wooden spoked wheels with wooden lollies which are bored radially to receive tenons on the outer ends of the spokes. It is a difficult matter to accurately :t'ornr wooden fellies and to maintain them in true circular form when once made. Consequently in the manufacture of wooden wheels there is considerable waste in structures rejected for lack of accuracy- On the other hand, metallic rims and follies are easily fashioned with a high degree of accuracy and uniformity, but are not adapted for assembling with spokes by the usual method in the manufacture of wooden wheels. This is for the reason that the Wooden follies are :t'ormed in half sections, permitting of the engagement of the spoke teams with the radial bores of the separate sections and then assembling and tightening by radial compression before engagement with the metallic rim. It is not de sirable to term ametallic telly in sections, and with a single annulus the spokes cannot be. engaged by radial movement without interference with each other. I have therefore devised a construction in which a single metallic annulus, forming the. telly, is provided with comparatively shallow spoke tenonengaging recesses, the spokes being en- .g'aged therewith while out oat radial alignment and then forced laterally into alignment.

As shown in Figure l. A is the telly which 3 is an elevation of the constructenons l) on the ends of the spokes E, said tenons being preferably ofilcsser diameter than. the body portion of the spoke so as to leave shoulders F for fitting against the portion of the rim surrounding the recesses C. To assemble the spokes and telly, the former ure'fil'st arranged in oblique relation to the plane of the wheel, their outer tenoned ends being inserted in the recesses C and their inner or huh ends being in contact with each other. Pressure is then applied laterally to the hub ends to force them into the planeof the wheel, as indicated in Figure (l, and this movement also forces the tenon ends radially outward so as to abut the same iirinly against the inner throes of the recesses C.

In the construction shown in Figures 2- and 3 the telly A forms a seat for a demountable rinr G, and is formed with the parallel outwardly-extending flanges H and H, one of which terminates in the flaring flange l. The other flange is provided with an inwardlyextending cylindrical flange J, which together with the flange it forms a seat for the demountable rim G. Bolts I: extend through the telly and aroused for engaging wedges or clamps L which secure the deniountable rim to the telly.

V/ith the construction as described, the

telly, being formedby dies, is round and true to a high degree of accuracy, and if the soohes are formed of uniform len th l a:

they willbear with equal pressure in eech or the sockets C. These sockets have suiii cient depth to preclude possibility of dis-- engagement and at the same time the depth is not too great to prevent engagement or" Hill the spokes by the method above described.

With the modified construction shown in Figure 5 the telly is provided with recesses C of a rounded or substantially hemispherical form, and the tenons D on the ends of the spokes are correspondingly lash ionetl. This will facilitate the assembly of the spokes with the telly, as the rounded form of the tenons will permit the same to ,inore, readily rock into engagement with the recesses.

Whet 1 claim as my invention is:

ire

as many prex-ssed-out closed, concave son-1t:

emme as there are spoke ends, said sockets fitting the shaped ends of respective wooden spokes and sealing the end-grain thereof, and said rim being circumferentielly tensioned upon and holding under compression the body of spokes, as a whole.

In testimony whereof I aflix my signature.
